Small notes: You MUST provide a link to the art. Even if it was done by 'anonymous', the curator would prefer to view the source of where the card idea came from, otherwise you could be infringing copyrighted art pieces without noticing; not to mention, if Zanz likes the artwork you have on the card, he would love to see where it came from for inspiration.
Also, in the table, replace the "
" symbol next to "ELEMENT" in the table with the word, Fire. This is so that newcomers can immediately recognize that the
symbol is equivalent to the element, 'Fire'.
That said, this idea almost mirrors Lava | Lava before it was changed to an environmental creature control effect. Although the idea may be 'inspired' by Eclipse, I would unfortunately have to say that this card idea is just a direct copy-and-paste version of
's trump card for boosting the attack of their creatures. Fire is already offensive as is, and this just increases the potency of the
's major strength.
Not to shut down your idea completely, but when I think of 'Hell', I imagine it to have a very disturbing consequence to all creatures on the field (including
monsters), rather than simply boosting attack power. After all, Phoenixes, Fire Spirits, and Dragons don't seem to fit in 'Hell' very well. Such majestic creatures shouldn't benefit from being placed into one of the most (believed) horrible places of eternal punishment.
Perhaps you can provide a special benefit to creatures with 'higher' attack than defense, and replace the stat bonus with something else... but that's just my two cents.
